Research Background

Democratic Party commissioned Public Opinion Programme at The University of Hong Kong in late December 2018 to conduct this survey on 7 to 11 January 2019 with 1,005 Cantonese-speaking Hong Kong citizens aged 18 or above. The goal is to gauge Hong Kong people’s views on the decision of Secretary of Justice on the UGL case.

The research instrument used in this study was designed entirely by the POP Team after consulting commissioning party. Fieldwork operations and data analysis were conducted independently by the POP Team, without interference from any outside party. In other words, POP was given full autonomy to design and conduct the survey, and POP would take full responsibility for all the findings reported herewith.

Survey date

:

7-11/1/2019

Survey method

:

Random telephone survey conducted with interviewers

Target population

:

Cantonese-speaking Hong Kong citizens aged 18 or above

Sampling method

:

Telephone numbers are randomly generated using known prefixes assigned to telecommunication services providers under the Numbering Plan provided by the Office of the Communications Authority (OFCA). Invalid numbers are then eliminated according to computer and manual dialing records to produce the final sample. If more than one subject had been available, the one who had his/her birthday next was selected.

Sample size

:

1,005 successful cases (including 612 landline and 393 mobile numbers)

Effective response rate

:

58.0%

Standard error

:

Less than 1.6% (At 95% confidence level, the maximum sampling error of all percentages should be no more than +/-3.2 percentage points)

Weighting method

:

The data has been rim-weighted according to figures provided by the Census and Statistics Department. The gender-age distribution of the Hong Kong population came from “Mid-year population for 2017”, while the educational attainment (highest level attended) distribution and economic activity status distribution came from “Women and Men in Hong Kong - Key Statistics (2018 Edition)”.


Research Design

Telephone interviews were conducted by interviewers under close supervision. All data were collected by our interviewers using a Computer Assisted Telephone Interview (CATI) system invented by the research team which allowed real-time data capture and consolidation. To ensure data quality, on top of on-site supervision, voice recording, screen capturing and camera surveillance were used to monitor the interviewers' performance.

 

Telephone numbers are randomly generated using known prefixes assigned to telecommunication services providers under the Numbering Plan provided by the Office of the Communications Authority (OFCA). Invalid numbers are then eliminated according to computer and manual dialing records to produce the final sample.

 

The target population of this survey was Cantonese-speaking Hong Kong citizens aged 18 or above. For landline sample, when telephone contact was successfully established with a target household, one eligible subject was interviewed. If more than one eligible subject had been available, selection was made using the “next birthday rule” which selected the person who had his/her birthday next. The survey was conducted on 7 to 11 January 2019. A total of 1,005 eligible respondents were successfully interviewed, including 612 landline and 393 mobile samples. The effective response rate of this survey was 58.0%, and the standard sampling error for percentages based on this sample was less than 1.6 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 3.2 percentage points at 95% confidence level.

 

To ensure representativeness of the findings, the raw data has been rim-weighted according to figures provided by the Census and Statistics Department. The gender-age distribution of the Hong Kong population came from “Mid-year population for 2017”, while the educational attainment (highest level attended) distribution and economic activity status distribution came from “Women and Men in Hong Kong - Key Statistics (2018 Edition)”.
